Ok I'm having some problems with my 09 hemi, please help me! Sometimes it gets a random knock but runs fine and the other day i started it up to leave work it was knocking and had a wierd squeaking noise that went along with the knock and was hesitating a little. No check engine light untill 3 days later and the truck would barely move. Code was a p0301 cylinder 1 missfire, so i went and got a new coil and 2 new plugs and unhooked the battery for about 30 minutes. It ran great untill I had to get on it pretty hard to pass some one then the light started once again flashing and dinging untill I let off the gas then started missing again. It now only comes on when I get on it. The dealer can't find anything so they say so im on my own

 

If you have an 09 isn't it still under warranty? Take it to the stealership and let them figure it out.

 

Ditto on 09 power train warranty

 

No its out I drive alot so i have 113000 miles on it

 

If this dealership can't figure it out, go to another one. Or a local shop. If you are out of warranty you don't have to go to a dealership.

 

'09's have a lifetime powertrain warrantee. Take it to a different dealer.

 

maybe second owner?

 

09 and 113k on it? DAMN!!!

 

Yeah, and I was bummed this morning when my 08 hit 52K.

Lifetime warranty doesn't cover electronics.

 

I had a similiar issue, was a bad injector # 7. Replaced under lifetime warranty.
